AI Technical Summary

Problems solved by technology

With the increase of color masterbatch or colorant, such as the addition of carbon black, wire breakage will easily occur and the workmanship will deteriorate. Color masterbatch can improve workmanship, but the blackness L value cannot be further reduced
The required deep black color rendering effect is not easy to achieve

preparation example Construction

[0031] A method of preparation of a base with a deep black chrysanthemum nylon fiber, followed:

[0032] The first step, a PE composite of carbon-based colorant: polyethylene PE addition amount and carbon-based colorant 40% blended extrusion to obtain a PE composite, wherein the carbon-based colorant is Vantablack carbon nanotube: carbon black = 1: 9, homogeneous blending, PE composites coated with a carbon-based colorant using a twin screw. like figure 2 The colorant is schematically dispersed in the PE internal homogeneous distribution.

[0033] In the second step, the PE composites are 30% mass percentage, and the solubilizer maleic anhydride is melt graft ethylene (PE-G-MAH) 5%, and PA6 65% melt is mixed, and the granulation is extruded to obtain a nylon high concentration. Black pellets make the carbon-based colorant form a discontinuous fine capsule in the masterbatch, such as figure 1 As shown, the fiber differently dispersed method is shown. figure 1 A is the colorant by P...

Embodiment 2

[0039] As in Example 1, only: the amount of nodes of nodes was 7%, and the amount of PA6 was added 63%, and the sea component material was selected with PET30%, the same blackness, and the colorant added less. See Table 2:

Abstract

The invention relates to a method for preparing a dark black ultrafine nylon fiber with a raw solution and a product thereof. The method for preparing a dark black ultrafine nylon fiber with a raw solution comprises the following steps: preparation of a PE composite material of carbon-based colorant, polyethylene The PE addition amount (40-60)% and the carbon-based colorant (60-40)% are blended and extruded to obtain a PE composite material; the PE composite material is (8-30)% by mass, the solubilizer is male Acid anhydride melt-grafted ethylene (PE-g-MAH) (2-5)%, PA6 (65-90)% melt blending, extrusion granulation to obtain nylon color masterbatch, so that carbon-based colorant is formed in the masterbatch Discontinuous fine capsules; preparation of nylon microfibers. A kind of raw solution obtained by the method of the invention is used to attach dark black polyester daisy superfine fibers, so that the ultrafine fibers obtained after the superfine fibers are opened, the black chromaticity L≤14, the color fastness to rubbing ≥4 grades, and the washing resistance Color fastness ≥ 4, light fastness ≥ 4, splicing and mutual dyeing degree ≥ 4, the cost is controllable, and it has a high market value.

Description

Technical field [0001] The present invention relates to a preparation method of a primary liquid with deep black ultra-fine nranar fibers and its products, which are in the field of printing and dyeing. Background technique [0002] According to the "Fiber Organon" survey: 2010-2015 The global microfiber leather production has maintained a composite growth rate of 9.6%, of which the global ultra-fine fiber leather production is 16.5 billion m. 2 It is expected that global microfiber leather production will exceed 200 million in 2020. 2 Reached 24 billion m 2 . At present, my country's island fiber has more than 200,000 tons, and the island microfiber leather has been vigorously developed in China as the fourth-generation synthetic leather. Yield is less than 40 million MM. 2 From 2017 annual output 120 million m 2 . [0003] Ultrafine fiber has become a hot spontaneous textile raw material for various textile production enterprises worldwide. Its use can effectively improve the p...
